For such systems, one video -output can be attached to a projector and the main presentation is -shown there. The second video output is attached to a small extra -monitor (or is just shown on the display of the computer) and shows, -for example, special notes for you. Alternatively, the two outputs -might be attached to two different projectors. One can then show the -main presentation on the first projection and, say, the table of -contents on the second. Or the second projection might show a version -translated into a different language. Or the seoncd projection might -alwyas show the ``previous'' slide. Or \ldots---I am sure you can -think of further useful things. - -The basic idea behind \beamer's support of two video outputs is the -following: Using special options you can ask \beamer\ to create a -\pdf-file in which the ``pages'' are unusually wide or high. By -default, their height will still be 128mm, but their width will be -192mm (twice the usual 96mm). These ``superwide'' pages will show -the slides of the main presentation on the left and auxilliary -material on the right (this can be switched using appropriate -options, though hyperlinks will only work if the presentation is on -the left and the second screen on the right). - -For the presentation you attach two screens to the system. The -windowing system believe that the screen is twice as wide as it -actually is. Everything the windowing system puts on the left half of -this big virtual screen is redirected to the first video output, -everything on the right half is redirected to the second video -output. - -When the presentation program displays the specially prepared -superwide \beamer-presentation, exactly the left half of the screen -will be filled with the main presentation, the right part is filled -with the auxilliary material---voilą. Not all presentation programs -support this special feature. For example, the Acrobat Reader 6.0.2 will -only use one screen in fullscreen mode on MacOS~X. You will have to -find out for yourself whether your display program and system support -showing superwise presentations stretching over two screens. - -\beamer\ uses the package |pgfpages| to typeset two-screen -presentations. Because of this, your first step when creating a -two-screen presentation is to include this package: -\begin{verbatim} -\documentclass{beamer} -\usepackage{pgfpages} -\end{verbatim} - -The next step is to choose an appropriate option for showing something -special on the second screen. These options are discussed in the -following sections. - -One of the things these options do is to setup a certain -|pgfpages|-layout that is appropriate for two-screen -presentations. However, you can still change hte |pgfpages|-layout -arbitrarily, afterwards. For example, you might wish to enlarge the -virtual pages. For details, see the documentation of |pgfpages|. - - -\subsection{Showing Notes on the Second Screen} - -The first way to use a second screen is to show the presentation -on the main screen and to show your notes on the second screen. The -option |show notes on second screen| can be used for this. It is -described on page~\pageref{command-notesonsecondscreen}. - - - -\subsection{Showing Second Mode Material on the Second Screen} - -The second way to use the second screen is to show ``a different -vesion'' of the presentation on the second screen. This different -version might be a translation or it might just always be the current -table of contents. - -To specify what is shown on the second screen, you can use a special -\beamer-mode called |second|. This mode behaves similar to modes like -|handout| or |beamer|, but its effect depends on the exact options -used: - -\begin{beameroption}{second mode text on second screen}{|=|\meta{location}} - This option causes the second screen to show the second mode - material. The \meta{location} of the second screen can be |left|, - |right|, |bottom|, or |top|. - - In detail, the following happens: When a new frame needs to be - typeset, \beamer\ checks whether the special option |typeset second| - is given. If not, the frame is typeset normally and the slides are - put on the main presentation screen (more precisely, on the logical - |pgfpages|-page number zero). The second screen (logical page number - one) shows whatever it showed before the frame was typeset. - - If the special frame option |typeset second| is given, after each - slide of the frame the frame contents is typeset once more, but this - time for the mode |second|. This results in another slide, which - is put on the second screen (on logical page number one). Then the - whole page is shipped out. - - The |second| mode behaves more like the |beamer| mode than - other modes: Any overlay specification for |beamer| will also apply - to |second| mode, unless an explicit |second| mode specification is - also given. In particular, |\only<1-2>{Text}| will be shown on - slides 1 and 2 in |second| mode, but only on the first slide in - |handout| mode or |trans| mode. - - \example -\begin{verbatim} -\documentclass{beamer} -\usepackage{pgfpages} -\setbeameroption{second mode text on second screen} -\begin{document} -\begin{frame}[typeset second] - This text is shown on the left and on the right. - \only<second>{This text is only shown on the right.} - \only<second:0>{This text is only shown on the left.} -\end{document} -\begin{frame} - This text is shown on the left. The right shows the same as for the - previous frame. -\end{frame} -\begin{frame}[typeset second] - \alt<second>{The \string\alt command is useful for second - mode. Let's show the table of contents, here: \tableofcontents} - {Here comes some normal text for the first slide.} -\end{frame} -\end{document} -\end{verbatim} - - \example The following example shows how translations can be added - in a comfortable way. -\begin{verbatim} -\documentclass{beamer} -\usepackage{pgfpages} -\setbeameroption{second mode text on second screen} -\DeclareRobustCommand\translation[1]{\mytranslation#1\relax} -\long\def\mytranslation#1|#2\relax{\alt<second>{#2}{#1}} -\title{\translation{Preparing Presentations|Vortr\"age vorbereiten}} -\author{Till Tantau} -\begin{document} -\begin{frame}[typeset second] - \titlepage -\end{frame} -\begin{frame}[typeset second] - \frametitle{\translation{This is the frame title.|Dies ist der Titel des Rahmens.}} - \begin{itemize} - \item<1-> \translation{First|Erstens}. - \item<2-> \translation{Second|Zweitens}. - \item<3-> \translation{Third|Drittens}. - \end{itemize} - \translation{Do not use line-by-line uncovering.|Man sollte Text nicht - Zeile f\"ur Zeile aufdecken.} -\end{frame} -\end{document} -\end{verbatim} -\end{beameroption} - -In the last of the above example, it is a bit bothersome that the -option |typeset second| has to be added to each frame. The following -option globally sets this option: -\begin{beameroption}{always typeset second mode}{|=|\meta{true or false}} - When this option is set to true, every following frame will have the - option |typeset second| set to true. -\end{beameroption} - - -\subsection{Showing the Previous Slide on the Second Screen} - -\begin{beameroption}{previous slide on second screen}{|=|\meta{location}} - This option causes the second screen to show the previous slide that - was typeset, unless this is overruled by a frame with the - |[typeset second]| option set. The idea is that if you have two - projectors you can always present ``the last two'' slides - simultaneously and talk about them. - - Using this option will switch off the updating of external files - like the table of contents. -\end{beameroption} - - - -%%% Local Variables: -%%% mode: latex -%%% TeX-master: "beameruserguide" -%%% End: |
